1. Field of the Disclosure
Embodiments disclosed herein generally relate to methods and apparatus to grip tubular members. More specifically, embodiments disclosed herein relate to an apparatus that is used to guide and grip one or more tubular members, such as oilfield tubular members as the tubular members are disposed downhole.
2. Background Art
In oilfield exploration and production operations, various oilfield tubular members are used to perform important tasks, including, but not limited to, drilling the wellbore and casing a drilled wellbore. For example, a long assembly of drill pipes, known in the industry as a drill string, may be used to rotate a drill bit at a distal end to create the wellbore. Furthermore, after a wellbore has been created, a casing string may be disposed downhole into the wellbore and cemented in place to stabilize, reinforce, or isolate (among other functions) portions of the wellbore. As such, strings of drill pipe and casing may be connected together, such as end-to-end by threaded connections, in which a female “pin” member of a first tubular member is configured to threadably engage a corresponding male “box” member of a second tubular member. Alternatively, a casing string may be made-up of a series of male-male ended casing joints coupled together by female-female couplers. The process by which the threaded connections are assembled is called “making-up” a threaded connection, and the process by which the connections are disassembled is referred to “breaking-out” the threaded connection. As would be understood by one having ordinary skill, individual pieces (or “joints”) of oilfield tubular members may come in a variety of weights, diameters, configurations, and lengths.

Additionally, the lifting apparatus 105 may be coupled below the traveling block 103 (and/or a top drive if present) to selectively grab or release a tubular member 111 as the tubular member 111 is to be raised and/or lowered within and from the derrick 102. As such, the top drive may include one or more guiding rails and/or a track disposed adjacent to the top drive, in which the guiding rails or track may be used to support and guide the top drive as the top drive is raised and/or lowered within the derrick. An example of a top drive is disclosed within U.S. Pat. No. 4,449,596, filed on Aug. 3, 1982, and entitled “Drilling of Wells with Top Drive Unit,” which is incorporated herein by reference.
Typically, a lifting apparatus 105 includes movable gripping members (e.g., slip assemblies) attached thereto and movable between a retracted (e.g., disengaged) position and an engaged position. In the engaged position, the lifting apparatus 105 supports the tubular member 111 such the tubular member 111 may be lifted and/or lowered, and rotated if so equipped, e.g., by using a lifting apparatus that is a tubular (e.g., casing) running tool connected to the quill of the top drive. In the retracted position, the lifting apparatus 105 may release the tubular member 111 and move away therefrom to allow the tubular member 111 to be engaged with or removed from the lifting apparatus 105 and/or the gripping apparatus 107. For example, the lifting apparatus 105 may release the tubular member 111 after the tubular member 111 is threadably connected to a tubular string 115 supported by the gripping apparatus 107 (e.g., slip assembly or “spider”) at the rig floor at the floor of the drilling rig 101.
Further, in an embodiment in which the drilling rig 101 includes a top drive and a tubular running tool, the tubular member 111 may be supported and gripped by the tubular running tool connected to the quill of the top drive. For example, the tubular running tool may include one or more gripping members that may move radially inward and/or radially outward. In such embodiments, these gripping members of a tubular running tool may move radially outward to grip an internal surface of the tubular member 111, such as with an internal gripping device and/or the gripping members of the tubular running tool may move radially inward to grip an external surface of the tubular member 111, such as with an external gripping device, however so equipped.
As such, the gripping apparatus 107 of the drilling rig 101 may be used to support and suspend the tubular string 115, e.g., by gripping, from the drilling rig 101, e.g., supported by the rig floor 109 or by a rotary table thereof. The gripping apparatus 107 may be disposed within the rig floor 109, such as flush with the rig floor 109, or may extend above the rig floor 109, as shown. As such, the gripping apparatus 107 may be used to suspend the tubular string 115, e.g., while one or more tubular members 111 are connected or disconnected from the tubular string 115.
Referring now to
The illustrated gripping device 201 includes a bowl 203 with a plurality of slip assemblies 205 movably disposed therein. Specifically, the slip assemblies 205 may be connected to a ring 207, in which the ring 207 may be connected to the bowl 203 through an actuator (e.g., actuator rods) 209. Actuator may be actuated, such as electrically actuated and/or fluidly (e.g., hydraulically) actuated, to move up and/or down with respect to the bowl 203, in which the slip assemblies 205 connected to the ring 207 may correspondingly move up and/or down with respect to the bowl 203.
The illustrated slip assemblies 205 are designed to engage and contact the inner tapered surface of the bowl 203 when moving with respect to the bowl 203. Bowl 203 is shown as a continuous surface but may comprise non-continuous surfaces (e.g., a surface adjacent to the rear of each slip assembly 205). Thus, as the slip assemblies 205 move up or down with respect to the bowl 203, the slip assemblies 205 may travel down along an inner surface of the bowl 203. With this movement, an inner surface (e.g., die) of the slip assemblies 205 will grip a tubular member 211 disposed within the gripping device 201. The slip assemblies 205 may have a gripping surface (e.g., teeth) on the inner surface to facilitate the gripping of the tubular member 211. After the tubular member 211 is supported by the gripping device 201, additional tubular members may be connected or disconnected from the tubular member 211.
As shown with respect to
A tubular string of tubular members may be heavy, in the magnitude of several hundreds of thousands of pounds. As such, the gripping devices handling these tubular strings, in addition to the drilling rig and other components thereof, must be equipped to handle such weight. Further, tubular members of the tubular string, such as casing, may have a relatively thin wall, in which the tubular members may be crushed or partially deformed if excessive force is applied by the gripping device. Additionally, the weight of the tubular string may be even further magnified, such as when drilling offshore, as the tubular string may need to extend through the water to reach the borehole, which may be in the magnitude of several thousands of feet, if not more. For example, the tubular string may have one or more different tubular members or tubular sections, such as including a section within the tubular string having casing, drill pipe, and/or a landing string, in which each of these sections of the tubular string may have different dimensions (internal diameter and/or external diameter) adding to the overall weight of the tubular string. Adding length to the tubular string only further increases the weight that the gripping devices, drilling rig, and other components thereof must be equipped to handle, an equipping process that may significantly increase the cost of for drilling.
To offset at least some of the weight of the tubular string (which may include a casing string or other tubular string hung from a distal end thereof), floatation modules have been developed that may be connected to or otherwise disposed about (e.g., about the OD of) a tubular member 311. One or more floatation modules 315 may be connected to the tubular member 311, such as by having a hinge formed on one side of the floatation module 315 that enables the floatation module 315 to, for example, clasp around the tubular member 311 from a lateral side thereof. Additionally or alternatively, a floatation module may be attached or applied to the tubular member, such as by applying as a coating or attached via other means, e.g., adhesive, to retain the floatation module stationary with respect to the tubular member. Depicted floatation modules 315 have a generally circular profile (e.g., a cylinder). However, floatation modules 315 may have any shape, such as a rectangular or hexagonal profile or spherical shape, that enables the floatation modules to connect to the tubular member 311.
A floatation module is commonly formed from a buoyant material or buoyant structure, such as having foam (e.g., high density foam) or plastic and/or having a housing with a fluid (e.g., gas) disposed therein for buoyancy. As such, this buoyant material or buoyant structure for the floatation module 315 may be used to offset at least some of the weight of the tubular member 311, e.g., from the drilling rig 101, and thus a tubular string altogether, as the floatation module 315 may be connected to the tubular member 311. A floatation module 315 may be used within the water, e.g., seawater of an offshore drilling operation, and/or a floatation module 315 may be disposed within a wellbore, including the riser, in land or offshore drilling operations. As such, a floatation module 315 may provide a buoyancy force when disposed within water and/or mud of a drilling operation, in which the buoyancy force of the floatation modules 315 may be used to offset at least some of the weight of the tubular string, e.g., from the drilling rig 101.
Further, a floatation module, may be used with a landing string, such as when a landing string is used to dispose (e.g., “land”) one or more tubular members, such as casing, within a wellbore in a deep water offshore operation. The landing string, which may exceed tens of thousands of feet in axial length to reach between the sea floor and the drilling rig (e.g., a floating drilling platform or ship), may include one or more floatation modules 315 connected thereto or otherwise disposed about to offset some of the weight of the landing string and the other tubular string (e.g., casing). As such, the floatation modules may relieve, at least a portion, of the stress applied to the landing string, other tubular string, and drilling rig equipment used for the operation.
However, as a floatation module may be formed from a generally buoyant material and/or as a generally buoyant structure (e.g., forming the floatation module with, at least a portion of, foam) a floatation module may lack strength and/or rigidity, e.g., the floatation module may be easily damaged. For example, a floatation module may be particularly susceptible to damage when assembling and/or disassembling a tubular string of tubular members together and/or disposing (e.g., raising or lowering) the tubular string within and/or through a gripping or supporting device (as discussed herein).
One example may be that, as a floatation module is disposed through a bore of a gripping or supporting device of a drilling rig, one or more of the components of the gripping or supporting device, such as the slip assemblies of the gripping device having a gripping surface (e.g., teeth) or other damage inducing surface or component of a gripping or supporting device, may contact and thus damage (e.g., dislodge) the floatation module. For further example, a gripping surface of a slip assembly (e.g., teeth) contacting a foam portion of a floatation module may damage (e.g., abrade or puncture) the flotation module. As such, damage to a floatation module may be magnified if a tubular member which the floatation module is connected to is not properly aligned within a bore of a gripping or supporting device during movement therethrough. Accordingly, there exists a need to prevent damage to a floatation module connected to a tubular member, as any damage to the floatation module may increase the loads applied to the drilling rig.
In one aspect, embodiments disclosed herein relate to an apparatus to guide a tubular member having a floatation module attached thereto. The apparatus includes a bowl forming a bore having a first opening formed at a first side of the bowl, a second opening formed at a second side of the bowl, and a tapered inner wall extending from the first opening to the second opening about a longitudinal axis, a slip assembly movably disposed within the bowl, a first guiding member disposed adjacent to the first opening of the bowl, and a second guiding member disposed adjacent to the second opening of the bowl.

Other aspects and advantages of the invention will be apparent from the following description and the appended claims.
Embodiments of the present disclosure will now be described in detail with reference to the accompanying Figures. Like elements in the various figures may be denoted by like reference numerals for consistency. Further, in the following detailed description of embodiments of the present disclosure, numerous specific details are set forth in order to provide a more thorough understanding of the claimed subject matter. However, it will be apparent to one of ordinary skill in the art that the embodiments disclosed herein may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.
In various aspects disclosed herein, embodiments disclosed herein generally relate to an apparatus that may guide a tubular member, such as guiding a tubular member when assembling a string of tubular members together. For example, embodiments disclosed herein relate to an apparatus that may be used to guide a tubular member. The tubular member, such as in one embodiment, may have one or more floatation modules disposed about and/or connected to the tubular member. The floatation modules may be used to manage the weight of the tubular member, in addition to manage the weight of the string of tubular members altogether. As such, the apparatus may be used to guide the tubular member into and through, for example, a gripping apparatus. In such an embodiment, the apparatus may thereby prevent, at least a portion of, damage from occurring to the floatation modules and/or the tubular member.
For example, if a tubular member having one or more floatation modules connected thereto is misaligned with a gripping apparatus when entering a gripping apparatus, one or more of the floatation modules may contact and be damaged against one or more components of the gripping apparatus (such as by having one or more of the floatation modules contact one or more of the slip assemblies of a gripping apparatus). However, an apparatus in accordance with embodiments disclosed herein may be used to guide and properly align the tubular member when entering a gripping apparatus, thereby preventing, at least a portion, of the damage from occurring to the tubular member and/or the floatation modules connected thereto. Further, in one embodiment the apparatus may be used to grip and support a tubular member, such as when suspending a string of tubular members from a drilling string, independent if the tubular member has a floatation module connected thereto.
Further, in one embodiment the apparatus may be used to allow a tubular member having one or more floatation modules connected thereto to pass through the apparatus, in which the apparatus may then grip and support (e.g., an end of) the tubular member after the one or more floatation modules have passed through the apparatus.
Thus, in one aspect, an apparatus in accordance with embodiments disclosed herein may include a bowl, a plurality of slip assemblies, and one or more guiding members. The bowl may have a bore or opening formed therethrough, and/or the plurality of slip assemblies may be movably connected to the bowl. Further, the apparatus may include one or more guiding members, such as having one or more guiding members disposed adjacent to one opening of the bore (e.g., defined by the bowl) of the apparatus and/or having one or more guiding members disposed adjacent to another opening of the bore. One or more guiding members may be disposed in the bore (e.g., defined by a bowl) of the apparatus, for example between adjacent slip assemblies, without departing from the spirit of the invention. One or more guiding members may be used to guide a tubular member, such as when a tubular member is being disposed within or through the apparatus. For example, the tubular member may have one or more floatation modules disposed thereabout and/or connected thereto, in which one or more of the guiding members may engage a surface of the floatation module to guide the flotation module into and/or through the apparatus. In one embodiment, one or more guiding members may guide a flotation module into and/or through an apparatus (e.g., spider) and also may guide the tubular that the flotation module is connected to through the apparatus (e.g., spider).
In one embodiment, the guiding members may include one or more rollers. A roller may be rotatably connected to the apparatus. As such, as when a roller engages a surface of a floatation module, the roller may rotate and roll against a surface of the floatation module. This movement may enable the roller to guide the floatation module and tubular member into and/or through the apparatus, thereby assisting in preventing, at least a portion, of damage occurring to the floatation module and/or tubular member by the apparatus.
The apparatus may include more than one guiding member. In such embodiments, a plurality of guiding members may be disposed adjacent to one or both ends of the bore (e.g., bowl). As such, the plurality of guiding members may be substantially equally spaced from one another about the longitudinal axis of the bowl. This configuration may enable the guiding members to apply substantially equal pressure to the floatation module and tubular member disposed within the apparatus. Further, the guiding members may be movable with respect to the apparatus, such as movable with respect to the longitudinal axis of the bore (e.g., bowl) of the apparatus. As such, the guiding members may be able to move radially with respect to the longitudinal axis of the bowl. Further, the guiding members may be able to move axially with respect to the longitudinal axis of the bowl.
As used herein, “connected” may refer to not only having two or more elements directly attached to each other, but connected may additionally refer to having two or more elements indirectly attached to each other. For example, as discussed more below, an apparatus in accordance with embodiments disclosed herein may have a guiding member connected to a bowl of the apparatus. As such, it should be understood that the present disclosure contemplates not only having the guiding member directly attached to the bowl, but the present disclosure additionally contemplates other structures and/or arrangements for the apparatus, such as by having a structure or member disposed between the guiding member and the bowl, in which the guiding member and the bowl are connected to each other through the other structure or member.

Guiding apparatus 401, which may be a spider as illustrated or an elevator, e.g., with the attachment of lifting bail or link eyes, includes a bowl 403 defining a bore 405 therein. The bore 405 may be formed about an axis 400 extending longitudinally through the apparatus 401. Specifically, the bowl 403 may be formed such that a top opening 407 of the bore 405 is formed at a top side of the bowl 403, and a bottom opening of the bore 405 is formed at the bottom side of the bowl (depicted in
The depicted apparatus 401 further includes a plurality of slip assemblies 421, in which the slip assemblies 421 are movable with respect to the bowl 403 (e.g., in-and-out of the bowl 403), such as by having the slip assemblies 421 movably connected to the bowl 403. Specifically, the depicted slip assemblies 421 are movable in a radial direction with respect to the axis 400 as well as being movable in a longitudinal direction along the axis 400. For example, by having the slip assemblies 421 movably connected to the bowl 403, the slip assemblies 421 may be able to “slide” towards and/or away from the axis 400, e.g., move along the inner wall of the bowl 403. As such, the slip assemblies 421 may be used to grip a tubular member, such as gripping an outer surface of a tubular member received within the apparatus 401. Slip assemblies 421 may be restricted from lateral movement in the bore (e.g., bowl), for example, while still allowing for movement towards and/or away from axis 400 (e.g., radial movement relative to axis 400 of the bore).
As shown, the slip assemblies 421 may be movably connected to a support ring 431. Support ring may be a “timing ring”, e.g., as discussed in the '169 application and the '072 application. For example, by using a slide mechanism 433, the slip assemblies 421 may be able to move in the radial direction with respect to the axis 400, in addition to the longitudinal direction along the axis 400, such as when the support ring 431 moves in the longitudinal direction. However, those having ordinary skill in the art will appreciate that other mechanisms or connections may be used to movably connect the slip assemblies to a support ring and/or the bowl. For example, in accordance with embodiments disclosed herein, a pin-and-link mechanism may be used to movably connect the slip assemblies to the support ring. As such, the present disclosure contemplates other structures and/or arrangements for the apparatus without departing from the scope of the present disclosure.
Apparatus 401 may include one or more guiding members 441, in which the guiding member(s) 441 may be disposed adjacent to one or more ends or openings of the bore (e.g., defined by bowl 403), slip assemblies 421, and/or support ring 431. In
As discussed above, the guiding member(s) 441 may be used to guide a tubular member into the apparatus 401. As such, the guiding member(s) 441 may be disposed adjacent to the bore of the apparatus 401 having axis 400 such that as a tubular member is received within the apparatus 401, the guiding member(s) 441 may engage a surface of the tubular member, or in other embodiments, a surface of a component connected to the tubular member such as a flotation module, to guide the tubular member into, out of, and/or through the apparatus 401. For example, in an embodiment in which a tubular member has a floatation module disposed thereabout and/or connected thereto, the guiding member(s) 441 may engage a surface of the floatation module to guide the tubular member into, out of, and/or through the apparatus 401. Though not particularly stated, those having ordinary skill in the art will appreciate that the present disclosure contemplates use with guiding a tubular member into, out of, through, and/or any other movement with an apparatus in accordance with embodiments disclosed herein.
As such, in one embodiment, the guiding member(s) 441 comprise one or more rollers, though those having ordinary skill in the art will appreciate any type of guiding member may be used to guide a tubular member within an apparatus in accordance with embodiments disclosed herein. For example, a guiding member may include a conveyor belt (not shown), such as a top and/or bottom set of three or more conveyor belts disposed about the bore of the apparatus 401. Rollers may be able to rotate, such as by having the roller rotatably connected (e.g., by bearing) to the support ring 431, as shown in
As shown in
Those having ordinary skill in the art, however, will appreciate that the present disclosure is not so limited, as the guiding member of the present disclosure may have multiple sizes, shapes, arrangements, and/or configurations. In one embodiment, one or more of the guiding member(s) may have a convex or a concave outer surface, e.g., in which the convex or concave surface is used to engage with the outer surface of a floatation module and/or tubular member. Alternatively, in another embodiment, one or more of the guiding member(s) may have a substantially cylindrical outer surface. Further, in yet another embodiment, one or more of the guiding member(s) may have a low coefficient outer surface, in which the low coefficient surface may enable a floatation module and/or tubular member to “slide” against the surface of the guiding member(s). Furthermore, additionally or alternatively to a roller, one or more of the guiding member(s) may have a sloped surface, such as by having a surface that is sloped towards the axis of the apparatus (e.g., to form a generally convergent surface, for example, converging towards an opening of the bore) to facilitate guiding a tubular member into the apparatus. Furthermore still, in one embodiment, one or more of the guiding member(s) may collectively comprise a ring, or at least a portion of a ring, in which the guiding member(s) may be able to move between multiple radial positions with respect to the axis of the apparatus. For example, in one embodiment, one or more guiding members may be disposed about an axis of the apparatus such that the guiding member(s) form a circular, or semi-circular, arrangement with respect to the axis of the apparatus (e.g., laterally adjacent). In such an arrangement, one or more of the guiding members may be movable with respect to the axis of the apparatus, such as movable radially (e.g., only radially) with respect to the axis of the apparatus. As such, multiple sizes, shapes, arrangements, and configurations are contemplated for one or more guiding member(s) in accordance with the present disclosure.
One or more of the guiding member(s) may be connected to the apparatus such that the guiding member(s) may move (e.g., be actuated) in the radial direction (e.g., at least the radial direction) with respect to the axis of the apparatus. In such an embodiment, the guiding member(s) may be movable between multiple radial positions with respect to the axis of the apparatus. Such guiding member(s) may be selectively locked into one or more of the radial positions, as desired. For example, as shown in
Guiding member(s) may be driven by an actuator, e.g., driven towards and/or away from the bore of the apparatus. An actuator may be mounted to a guiding member(s) via linkage or other ways known in the art. An upper and/or a lower set of laterally adjacent guiding members may comprise an actuator, to drive guide member(s) towards and/or away from the bore of the apparatus. As such, an actuator may have a sensor and/or a controller coupled thereto and/or with each other, in which a sensor may be able to communicate the position of a guiding member and the controller may be able to send signals to control the actuator, thereby enabling the actuator to move the guiding member to a desired position. Referring now to
In one embodiment, guiding member(s) having actuators connected thereto may be controlled, such as controlled by a processor or other control system, to dispose one or more of the actuated guiding members to a desired location (e.g., a desired distance from the axis of the bore of the apparatus or from the surface of a tubular disposed in the bore the apparatus). For example, guiding members (e.g., laterally adjacent guiding members) may be actuated, such as by a processor/computer or by an operator, to move and dispose the guiding members to a substantially uniform radial distance relative to the axis of the bore of the tool, such as shown in
In one embodiment, in an inward radial position, the guiding member(s) may be extendable further radially inward than the gripping portion of the slip assemblies with respect to the axis of the apparatus. In an outward radial position, the guiding member(s) may be extendable further radially outward than the gripping portion of the slip assemblies with respect to the axis of the apparatus. Further, those having ordinary skill in the art will appreciate that, though one or more guiding members may have an actuator attached thereto, in other embodiments without actuators attached thereto, guiding members may be movable, such as movable between an inward radial position and an outward radial position. Further, in accordance with one or more embodiments disclosed herein, one or more guiding members may not be movable, such as with respect to the axis of the apparatus. In such an embodiment, the guiding member(s) may be disposed in a desired radial position, such as by having the guiding member(s) disposed in an inward radial position. As such, those having ordinary skill in the art will appreciate that the present disclosure contemplates multiple orientation and arrangements for the guiding members, as the guiding members may be movable, non-movable, and/or may include one or more actuators.

The apparatus 501 may include one or more guiding members 541, in which, as discussed above, the guiding member(s) 541 may be disposed adjacent to one or more sides of the bowl 503. As shown in
A plate assembly 551 may include one or more plates included therein, if desired, to connect to the guiding member(s) 541. For example, in this embodiment, the plate assembly 551 includes a first plate 555 and a second plate 557 connected to each other using one or more struts 591. The first plate 555 and the second plate 557 may be disposed substantially parallel with respect to each other, and a strut may be connected between the first plate 555 and the second plate 557 such that a gap is formed between the first plate 555 and the second plate 557 of the plate assembly 551. As such, this arrangement may enable one or more guiding member(s) 541 to be disposed between the first plate 555 and the second plate 557 of the plate assembly 551, such as disposed within gaps formed within the plate assembly 551. However, those having ordinary skill in the art will appreciate that the present disclosure is not so limited, as other structures and/or arrangements may be used for the apparatus without departing from the scope of the present disclosure, such as a plate assembly having only one plate or more than two plates, or by not including a plate assembly at all and having the guiding member(s) connect to the bowl of the apparatus.
Further, the plate assembly 551 may removably connect to the bowl 503 of the apparatus 501, if desired. As shown in
Furthermore, one or more components of an apparatus in accordance with embodiments disclosed herein may be formed into one or more sections or unitary. For example, in select embodiments, the bowl may be formed into more than one section. Specifically, as shown in
Referring now to
As with the embodiment shown in
Further, the apparatus 601 may include a bowl 603 and a plurality of slip assemblies 621, in addition to a support ring 631 and one or more guiding member(s) 641. The guiding member(s) 641 may be substantially equally spaced from one another about the longitudinal axis of the bowl 603. As such, and as described above, the guiding member(s) 641 may be used to guide the tubular member 693 when the tubular member 693 is being disposed adjacent to and/or within the apparatus 601. For example, as the floatation module 695 is disposed about and connected to the tubular member 693, one or more of the guiding member(s) 641 may engage a surface of the floatation module 695 to guide the tubular member 693 into and/or through the apparatus 601.
As shown and discussed above, an apparatus in accordance with the present disclosure may be used to grip or support one or more tubular members. For example, as shown in one or more embodiments discussed above, the apparatus may include one or more slip assemblies, in which the slip assemblies may be used to grip a tubular member. As such, an apparatus in accordance with the present disclosure may be similar to the gripping apparatus shown and disclosed within the '169 application and the '072 application, both of which were incorporated by reference above. Further, an apparatus in accordance with the present disclosure may be any other gripping or supporting apparatus known in the art. For example, in addition or in alternative to a gripping apparatus, a supporting apparatus may be used in accordance with guiding embodiments disclosed herein that supports one or more tubular members within a drilling rig, such as supporting a tubular string of tubular members suspended from a drilling rig. An example of a supporting apparatus is disclosed within U.S. Pat. No. 6,651,737, filed on Jan. 24, 2001, and entitled “Collar Load Support system and Method,” which is incorporated herein by reference above. E.g., the supporting apparatus of the 6,651,737 patent could be outfitted with guiding member(s), e.g., guiding members disposed about the top and/or bottom openings of the apparatuses disclosed therein.
Referring now to
Further, the apparatus 701 may include one or more guiding members 741 disposed adjacent to one (e.g., top or bottom) opening of a bore of the apparatus 701, or adjacent to each of the two openings (e.g., top and bottom) of the apparatus 701. The apparatus 701 may include a plate assembly 751, in which the one or more guiding members 741 may be connected (e.g., fixed or movably (optionally movable via an actuator)) to the plate assembly 751. As such, the guiding member(s) 741 may be used to guide the tubular member 793 when the tubular member 793 is being disposed within the apparatus 701, such as by having the guiding member(s) engage a surface of the floatation module 795 connected to the tubular member 793. Further, the plate assembly 751 shown in
Accordingly, in accordance with one or more embodiments disclosed herein, as the apparatus 741 may include guiding members 741 disposed adjacent to the openings of the apparatus 701, the guiding members 741 are used to contact and guide a tubular member into, within, and/or through the apparatus 741. As such, when guiding the tubular member, guiding members 741 from the top of the apparatus 701 and guiding members 741 from the bottom of the apparatus 701 may be used to establish at least two points-of-contact with the tubular member, such as axially and/or radially spaced points-of-contact. For example, one point-of-contact with the tubular may be axially spaced from another point-of-contact with respect to the axis of the apparatus. Further, in another example, one point-of-contact with the tubular may be radially spaced from another point-of-contact with respect to the axis of the apparatus. By establishing two points-of-contact with the tubular member with the guiding members, this may prevent the tubular member, and other components attached to the tubular member (e.g., floatation module) from contacting the apparatus 701, such as from having the floatation module from contacting a slip assembly (e.g., the gripping surface thereof) of the apparatus 701. For example, at least two axially spaced points-of-contact may prevent a tubular member from contacting a slip assembly of an apparatus 701. Further, at least two radially spaced points-of-contact may be used to guide a tubular member through the bore of an apparatus, for example, such that the guiding members 741 of the apparatus 701 are the only elements that may be able to contact the tubular member and/or buoyancy module(s) connected to the tubular member e.g., when the slip assemblies are in the retracted position. Accordingly, at least two points-of-contact with the tubular member may be used to have a desired orientation and movement of the tubular member into, within, and/or through an apparatus in accordance with one or more embodiments disclosed herein. The slip assemblies may be retractable to a radial distance from the axis to prevent contact with any outer diameter protrusion of a tubular. For example, as discussed below with reference to

Specifically, the apparatus 801 may include a bowl 803 with a plurality of slip assemblies 821 movably connected thereto (e.g., disposed therein), in which the plurality of slip assemblies 821 may move radially inward and longitudinally downward with respect to the longitudinal axis of the bowl 803, e.g., when the tubular member 893 is disposed within the apparatus 801. For example, the slip assemblies 821 may move radially inward and longitudinally downward from a first position, such as a retracted position shown in
Further, the depicted tubular member 893 has a floatation module 895 disposed about and connected to the tubular member 893. When a floatation module 895 is disposed into the apparatus 801, the plurality of slip assemblies 821 may be disposed at a first position, such as the retracted position shown in
Further, those having ordinary skill in the art will appreciate that in accordance with one or more embodiments of the present disclosure, one or more guiding member(s) may be disposed adjacent any pipe gripping or supporting apparatus known in the art. As such, the guiding member(s) may be used to guide tubular members, such as tubular members having floatation modules attached thereto, through any gripping or supporting apparatus. In an embodiment, in which guiding member(s) are disposed adjacent to the top side of the apparatus and the bottom side of the apparatus, the guiding member(s) on both the top side and bottom side of the apparatus may be used to guide and prevent contact of the tubular member with other portions of the apparatus.
Further, as shown in

As discussed above, the apparatus 901 may be used to grip and support a tubular member. For example, the apparatus 901 may include a bowl 903 with the plurality of slip assemblies 921 movably connected thereto, in which the plurality of slip assemblies 921 may move radially inward and outward and longitudinally upward and downward with respect to the longitudinal axis of the bowl 903. As such, the slip assemblies 921 may move radially inward and longitudinally downward from a first position, such as the retracted position shown in
Further, a gripping apparatus in accordance with one or more embodiments disclosed herein may include one or more protectors coupled to the gripping apparatus, in which the protectors may be used to protect one or more tools, floatation modules, and/or any other component disposed within the gripping apparatus. For example, as shown in
As shown, as the protectors 971 are movable with respect to the apparatus 901, the protectors 971 may move as the slip assemblies 921 move within the apparatus 901. As such, as shown in
As shown, a protector 971 may be disposed on each side of each slip assembly 921 included with the apparatus 901. However, those having ordinary skill in the art will appreciate that the present disclosure is not so limited, as the present disclosure contemplates multiple structures and arrangements for protectors within a gripping apparatus. For example, in one embodiment, a protector may be disposed on only one side of a (e.g., each) slip assembly within the apparatus, or, in another embodiment, only one protector may be included within the apparatus altogether. As such, multiple structures and arrangements may be used for the protectors of an apparatus without departing from the scope of the present disclosure.

The gripping apparatus 1001 may be used to guide the tubular member 1093 with one or more guiding members 1041, in which the guiding members 1041 may be movably connected to the apparatus 1001. For example, the guiding members 1041 may be able to rotate with respect to the apparatus 1001. However, as discussed above, the guiding members 1041 may be able to move with respect to the longitudinal axis of the apparatus 1001, such as move radially with respect to the longitudinal axis of the apparatus 1001. As such, in
In one embodiment, as the guiding members may be radially movable with respect to the longitudinal axis of the apparatus, the guiding members may be moved radially to prevent damage to a tubular member, to prevent damage to a tool, to prevent damage to a floatation module attached to a tubular member, and/or to prevent damage to any other component that may be disposed within and/or through a gripping apparatus in accordance with one or more embodiments disclosed herein. As such, as shown in
As such, the guiding members 1041 may be moved further radially inward with respect to the longitudinal axis of the apparatus 1001, and/or the slip assemblies 1021 may be moved further radially outward, to prevent interference (e.g., damage) to the tubular member 1093 and components thereof, such as the collar 1097 or a floatation module. For example, the guiding members 1041 may be disposed in a second radial position, which is closer to the longitudinal axis than the first radial position. In this radial position, the tubular member 1093, and any component attached thereto, may be prevented from interfering with the slip assemblies 1021 within the apparatus 1001. Further, in one or more embodiments, the slip assemblies 1021 may be moved radially outward with respect to the longitudinal axis of the apparatus 1001 such that the tubular member 1093, and any component attached thereto, may be prevented from interfering with the slip assemblies 1021 within the apparatus 1001. Accordingly, even though a component may be attached to a tubular member when in use with an apparatus or method in accordance with the present disclosure, the guiding members and/or the slip assemblies may be used to prevent interference with the tubular member (and components thereof) and the slip assemblies of the apparatus. For example, in one embodiment, even though a tubular member may have a component attached thereto, as the component passes within, into, and/or through the apparatus, the guiding members and/or the slip assemblies may be positioned to prevent interference with the component of the tubular member and the slip assemblies.
Accordingly, in one embodiment, one or more of the guiding members of the present disclosure may be disposed at a location that is radially closer to the longitudinal axis of the apparatus than the location of one or more slip assemblies of the apparatus. As such, the guiding members of the present disclosure may be used to prevent damage to a tubular member, a tool, a floatation module, and/or any other component that may be disposed within and/or through a gripping apparatus in accordance with one or more embodiments disclosed herein. As discussed above, the guiding members may be movable through the use of an actuator coupled thereto. Further, as discussed above, one or more protectors may be disposed adjacent to one or more of the slip assemblies, such as to prevent contact between the slip assemblies and a tubular member and/or a component attached thereto. However, those having ordinary skill in the art will appreciate that the present disclosure is not so limited, as other embodiments, arrangements, and components may be used for an apparatus in accordance with embodiments disclosed herein without departing from the scope of the present disclosure.
As discussed above, one or more (or all) of the guiding members may be driven by an actuator, e.g., driven towards and/or away from the longitudinal axis of the bore of the gripping apparatus. As such, in one embodiment, the guiding members may comprise an actuator to move the guiding members between the first position, shown in
Accordingly, aspects of embodiments disclosed herein, such as controlling and/or moving one or more guiding members, slip assemblies, actuators and/or controlling and moving any other components of a gripping apparatus, may be implemented on any type of control system, e.g., hydraulic, pneumatic, electric and/or mechanical system. A control system may comprise sensor(s) and/or actuator(s). A control system may comprise a computer regardless of the platform being used. For example, as shown in
It should be understood that the present disclosure contemplates a method to guide a tubular member, such as when assembling a string of tubular members together, e.g., using a gripping apparatus.
